Description
Technical field
The present invention relates to a kind of Electical connector, it has first contact that comprises pin jack, second contact mutually opposed and moulding in the same manner that can move with respect to described first contact and the auxiliary contact that is guided movably in pin jack.
Background technology
This Electical connector for example can be known from the publication document JP-10-308143 of Japan.Electical connector there has first and second contacts, and wherein auxiliary contact is guided in the pin jack of described first contact movably.Auxiliary contact slides in pin jack.
This with described guide design on a kind of guide post around auxiliary contact itself, described guide post passes first contact movably at the bottom section of pin jack.The supporting structure of guide post is designed on relatively short portion's section.
Only with auxiliary contact mating reaction the time, can stop the guide post run-off the straight.Auxiliary contact thereby be used to mechanical guiding on the one hand, and be used to the contacting that conducts electricity on the other hand.The surface of the contacting that is designed to conduct electricity, thus will bear electricity with the load of machinery.
Because mechanical wear, electrical property can be adversely affected.Otherwise the function of machinery also can be subjected to the adverse influence of electro ultrafiltration.
Summary of the invention
Therefore the technical problem to be solved in the present invention is, a kind of Electical connector is provided, it can reduce Electical connector that power on the interactional possibility of function machinery.
According to the present invention, described technical problem is solved like this at the Electical connector that this paper starts described type, that is, the guiding of described auxiliary contact electric insulation ground is mobile.
Electical connector with first and second contacts that can move relative to each other is used in the turn-off current circuit or sets up on the electric switching system of current circuit.When carrying out relative motion between two contacts, can realize the foundation of current circuit by means of the direct or indirect contacting of two contacts.Can adopt the branch of the contact of the mutual contacting turn-off current circuit that comes.In a kind of project organization of first contact with pin jack, can advantageously set, this pin jack is equipped with contact member, and described contact member is sleeved on a kind of with respect to pin jack on the outer surface mutually opposed and second contact of moulding in the same manner when contact device is in on-state.Two contacts can be moved relative to each other along straight line, thereby make second contact to insert in the pin jack of first contact on not canting ground.By means of a kind of in pin jack the auxiliary contact of guiding movably, following possibility is provided, that is, the contacting between two contacts, the auxiliary contact that can connect by the centre earlier be realized.The mobile axis of auxiliary contact, can preferred parallel in the mobile axis of the contact that can move relative to each other.Like this, can protect pin jack to avoid influence as the arc phenomenon that separates at contact or occur when closed.At this, if for auxiliary contact has set the zone of for example being made up of ablation resistant material, be favourable.The material of described anti-ablation has higher resistance intensity for the contact material that is used for constituting contact of arc phenomenon than other.
If stipulated the guiding of auxiliary contact electric insulation ground, can just can concentrate on worthily on the auxiliary contact by arc phenomenon so.So, can realize that auxiliary contact is to the protective effect of first contact.In addition, can prevent the leakage current circuit by means of the guiding of electric insulation.Can prevent from the mechanical device of the guiding that is taken as auxiliary contact, electric discharge phenomena occurring with this.This leakage current circuit has been stopped in the guiding of electric insulation.
Another kind of favourable design can stipulate that described auxiliary contact is guided mobile in the insulating component that is held by described pin jack.
Be laid in the insulating component in the pin jack, for example to install in the pin jack in the inner surface.So, can allow the outer surface of auxiliary contact be close on the insulating component.Can be with the insulating case in for example pin jack shell zone or the shell of segmentation form (for example slide plate or point), as insulating component.Insulating component can have the surface that for example is made of plastics, and auxiliary contact is close on the described surface, and described surface has the electric insulation effect.For example polyethylene or similar plastics all are the plastics that are suitable for.Described plastics make it possible to the auxiliary contact of low frictionally guiding, thereby can move auxiliary contact easily.In addition, auxiliary contact has advantageously stoped itself run-off the straight or canting in insulating component with the outer surface channeling conduct.
In addition, can advantageously set, auxiliary contact at least when contact is in released state, by contact member conductively with the first contact contacting.
According to the relative motion between two contacts, auxiliary contact carries out its guiding in the pin jack of first contact mobile.During the guiding of carrying out electric insulation is moved and when auxiliary contact and the first contact contacting, auxiliary contact and first contact are by identical current potential.But because the insulation of auxiliary contact guiding is mobile, the transfer of current potential is without the mechanical device that is designed to guide auxiliary contact.The substitute is, make up the contacting circuit between auxiliary contact and first contact outside a kind of definite guiding that is in insulation, thus provide between first contact and the auxiliary contact a kind of do not allowing the leakage current circuit through the situation of the mechanical device that is used for guiding under the transfer of current potential.Contact member can impel auxiliary contact and the direct contacting of first contact at this, thereby a kind of contacting with very little transmission resistance is provided.Because current potential is identical, can not set up electric field between first contact and auxiliary contact.Therefore, can between auxiliary contact and first contact, make up a field free region.Especially can when correspondingly contact is assisted in design, make pin jack itself keep open to the field.
Another kind of favourable design can be set, and contact member can be according to the on off state of Electical connector, with auxiliary contact or the direct contacting of second contact.
The direct contacting of auxiliary contact or second contact and contact member makes contact member when Electical connector is in connection and off-state, can both be used to constitute the contacting circuit.Like this, for example can be when on-state realize that by contact member the direct electric contact between first and second contacts connects.When off-state, when just between two contacts, existing conduction to separate, can adopt contact member to set up direct contacting with auxiliary contact.Therefore contact member can finish different tasks under different on off states.When Electical connector was in on-state, contact member was used as a part that is structured in the current circuit between first and second contacts.When Electical connector was in off-state, contact member is used as transferred to the transfer device of assisting on the contact with current potential from first contact.Therefore, can realize on the one hand the guiding of electric insulation of auxiliary contact and the transfer that guarantees current potential by contact member, wherein except contact member, do not need additionally to add contact element, because this contact member when switching on and off state, can both be used to set up the contacting circuit.
At this, direct contacting is set at, contact member makes first contact and auxiliary contact, and first contact and second contact directly are connected to each other in order to form the contacting circuit.Directly contacting has reduced the quantity of the contact point that is connected in series, and has limited contact resistance thus.Can further stipulate, during a kind of switch state is become another kind of on off state, between first contact and auxiliary contact and second contact, have direct contacting simultaneously.Can use the direct contacting of first and second contacts and auxiliary contact, in order to will assist contact from be implemented in the current circuit between first and second contacts, to separate or middle being connected in the current circuit that is implemented between first and second contacts incessantly.
Another kind of favourable design can be set, and the ambulant director element that described auxiliary contact is limited described auxiliary contact passes.
If the employing director element so just provides the possibility that the mobile route of auxiliary element is set.Providing thus for example can be by means of the auxiliary contact of insulating component electric insulation ground guiding and the ambulant possibility that limits auxiliary contact by director element.Director element thereby be used as the limiting element of auxiliary contact.Described limiting element has stoped auxiliary contact to come off out from pin jack.If possible, can also set, the guiding to auxiliary contact electric insulation has only guaranteed the guiding to it.
Auxiliary contact is owing to director element is difficult to take place coming off of unstructuredness.
Director element can be used as backstop and use, thereby limit the mobility of assisting contact by means of director element itself.When the jack mouth direction of assisting contact towards pin jack moves, stoped auxiliary contact from pin jack, to move by means of director element.For this reason, director element can have backstop, and auxiliary contact collides on the described backstop, limits the movement of auxiliary contact with this.Can set at this, auxiliary contact is laid with respect to director element electric insulation ground, and only when touching the backstop of director element, the just connection of a kind of direct conduction of formation between director element and auxiliary contact.Auxiliary contact can be for example according to the mode of matched in clearance around director element, thereby in order to reach the purpose of electric insulation, director element and around auxiliary contact between enough spacings are provided.Can be with body rib outstanding on the director element, the backstop of being used as auxiliary contact uses, and wherein strikes moment on the backstop of director element at auxiliary contact, just between director element and auxiliary contact, can reach contacting by a kind of circuit with conductive capability.
Another kind of favourable design can stipulate that auxiliary contact is by spring-loaded, and has be used to the cannelure that holds spring.
Load by spring, be of value to auxiliary contact is fixed on the terminal location.Thereby for auxiliary contact, spontaneously be moved, be impossible.The movement of auxiliary contact can overcome the power that is produced by spring and carry out.Spring can be contained in the cannelure of for example assisting contact.Like this, the ground that spring force can be symmetrically distributed imports in the auxiliary contact, and can be as far as possible point-blank be applied to along the spring force of the mobile axis directive effect of auxiliary contact and assists on the contact.Cannelure can have for example cross section of rectangle, wherein cannelure itself be sealing ground around.Spring can have helical spring shape, and it is oriented coaxial and be close on the bottom land of cannelure with cannelure.
Can also set at this, cannelure is around director element.
When director element by cannelure around the time, following possibility is provided, that is, spring can be directed to element equally and pass.Like this, the moving direction that the effect of power can be parallel to auxiliary contact imports in this auxiliary contact.Can set auxiliary contact and the director element spacer is liftoff moves along mobile axis.The movement of auxiliary contact can enter pin jack and be triggered by for example second contact.This moment second contact pass the jack mouth enter pin jack and along director element towards with the jack mouth away from the direction of pin jack bottom promote auxiliary contact.For example can stipulate for this reason, director element medially is laid in the pin jack.
Can advantageously set in addition, auxiliary contact has and compresses with the annular of second contact that the zone is relative puts and the contacting zone of the annular of moulding in the same manner.
In the connection process, can make the regional zone that compresses with second contact of contacting of the annular of auxiliary contact that contacting takes place in advance earlier, thereby can connect under the situation of auxiliary contact in the centre, between first and second contacts, form current circuit earlier.When arcing, just guaranteed that erosion appears at earlier on the auxiliary contact, especially compressing on the zone at its annular contacting zone and second contact.Annular mutually opposed and moulding second contact in the same manner compress the zone time, can utilize the contacting zone of the annular of auxiliary contact, in order to implement the movement of the auxiliary contact caused by the relative motion between the contact, and move auxiliary contact towards the bottom direction of pin jack.Along with the contacting zone of auxiliary contact and the contacting that compresses the zone of second contact, to exist direct electric contact to connect between auxiliary contact and first contact, otherwise, can realize the electric contact connection by the middle auxiliary contact that connects indirectly between first and second contacts.
When second contact moves forward, that is to say, when moving of auxiliary contact begins, auxiliary contact moves towards the bottom direction of pin jack, wherein, first contact is connected the direct contacting of and then being transferred between first contact and second contact with the direct electric contact of auxiliary contact.Therefore, spin off the middle current circuit of auxiliary contact between two contacts of Electical connector that connects, and no longer be the part of the current circuit between first and second contacts.Though auxiliary contact also continues directly with second contact and has contacting with first contact indirectly, has so only realized potential transfer to assisting on the contact.Guiding by means of to the electric insulation of auxiliary contact has prevented that parallel current circuit is through auxiliary contact and mechanical guide means thereof.Auxiliary contact originally no longer is the part by the current circuit of the formation of the Electical connector between first and second contacts after switching.Described switching can be carried out incessantly at this.Otherwise, when Electical connector disconnects, can will assist contact to be connected to medially between the direct contacting of two contacts that will exist, thereby set up the indirect contacting of two contacts by auxiliary contact.This switching also can be carried out incessantly.Guaranteed that thus when current circuit to be disconnected is interrupted, arc phenomenon will appear at the contacting zone of auxiliary contact and compressing between the zone of second contact.
When Electical connector is in off-state, auxiliary contact can pass the jack mouth of first contact towards the direction of second contact, thereby guaranteed that when second contact moves towards the pin jack direction of first contact, second contact will collide on the auxiliary contact in advance.Otherwise, in the disconnection process, will assist the separation of the current circuit between contact and second contact.Arc phenomenon thereby concentrate on described contacting zone and compress on the zone.
In addition, can advantageously set, second contact has the guiding jack, and described guiding jack will be passed on the director element in the connection process.
Guiding jack in second contact makes and director element can be applied in the pin jack of first contact, thereby makes Electical connector firm.Therefore can on director element, lead to second contact, and between the outer surface of pin jack and second contact, carry out electric contact and connect.Outside the pin jack of second contact and first contact, between the inner surface, corresponding interval can be set, thereby make the contact member be laid in there flexibly to be out of shape, and guarantee on the inner surface of the pin jack of first contact or have enough thrusts at the outer surface of second contact.By adopting director element that second contact is led, prevented that the strain zone of contact member from suffering owing to second contact canting ground imports the unallowed distortion that causes in the pin jack.Like this, for example can guarantee the coaxial orientation that has between two contacts.
Director element is being undertaken two tasks in Electical connector, constitute the backstop of auxiliary contact on the one hand, in order to the mobility of auxiliary contact is limited.On the other hand, director element has formed a bearing, in order to stop the second contact generation canting that imports in the pin jack.Can make the second contact direct collision to director element at this, thereby even during relatively moving between two contacts, also can guarantee the coaxial orientation that it is mutual.
Another kind of favourable design can be set, and the guiding jack has radially outstanding induction element.
In the guiding jack, lay a kind of radially outstanding induction element, make and the bearing-surface of guiding jack on director element can be restricted on the outstanding induction element.Can make second contact that collides on the director element have mechanical stability like this, on the one hand.Reduced the sliding friction that occurs on the other hand.Can adopt induction element conduction or electric insulation to be used as described induction element, they for example are configured to the form to the ring tied up of guiding jack.The induction element of annular radially stretches in the guiding jack cross section of second contact.Adopting especially, plastic hoop is proved to be to suit as induction element.
Can advantageously set in addition, the zone that auxiliary contact and second contact are in contact with one another has the coating of anti-ablation.
The coating of described anti-ablation has higher stability for arc phenomenon than other contact materials of first and second contacts.By in the zone that is in contact with one another of auxiliary contact and second contact, namely the contacting of annular annular regional and second contact mutually opposed and that make up in the same manner with respect to the contacting zone of annular compresses on the zone, use the coating of anti-ablation, a kind of clear and definite surface that has resistivity for arc phenomenon is provided on the one hand.The coating of this anti-ablation also can have enough mechanical stabilities, thereby makes mechanical force to be received by this coating.Especially the coating of described anti-ablation can also be used for the power transmission, move in order to auxiliary contact can be overcome by spring-loaded elastic force ground.
Another kind of favourable design is set, auxiliary contact locking pin jack.
By means of auxiliary contact locking pin jack, make it possible to dielectric ground shielding jack mouth.Although thus can be laid in the pin jack might be aspect dielectric defectively moulding and be laid in the pin jack, still may impel electric field that the contact member of distortion takes place, shield.Except shield pin jack by means of auxiliary contact, the jack mouth of locking pin jack also makes contact member that a kind of protection of machinery has been arranged.Make that thus mechanical force is difficult to directly to be applied in the pin jack or contact member is difficult to be polluted.
Can advantageously set in addition, auxiliary contact is with the pin jack of director element locking.
If director element with the pin jack of auxiliary contact locking, can be laid the space that is used for holding the annular of assisting contact so around director element in pin jack.Auxiliary contact can have substantially ringwise or be substantially the profile of hollow cylindrical.The movement of auxiliary contact is to carry out along the longitudinal axis of director element or the longitudinal axis of pin jack, and wherein director element is used for guiding second contact.
Can advantageously set in addition, described contact member is the contact ring of the elastically deformable that guiding is moved in the groove of described pin jack.
The contact member of the contact ring of elastically deformable being used as the groove that is arranged in pin jack uses, and making can be in narrow space, provides a large amount of contacting position between first and second contacts for use.Contact ring can be implemented as various.So, for example helical spring can be bent to the annular, thereby based on a large amount of wire turn of helical spring, provide respective numbers between first and second contacts or the contacting position between first contact and auxiliary contact.In addition, can also adopt to have corresponding outstanding contact finger or the contact ring of contact chip, described contact finger or contact chip can with first contact and auxiliary contact, perhaps take place directly to electrically contact with first contact and second contact.Groove in the pin jack should be coaxially around the longitudinal axis of pin jack and simultaneously also around director element.Slot cross-section should be complementary with the shape of applied contact ring.Like this, for example the slot cross-section of dovetail groove shape, rectangular shape, groove shape etc. can obtain to use.Contact ring spring is arranged can be built in the groove at this, thereby can connect the spring of contact ring as the electric contact of two contacts on the one hand.Then can also the spring of contact ring be applied on the other hand, so that contact ring can be positioned to form fit in the cover, and prevent that contact ring from radially and axially coming off out from pin jack.

The central authorities of pin jack mouth 14 are directed to element 6 and pass.In the annular gap that resides between director element 6 and first contact 1, will assist contact 7 to be laid in the pin jack 3.Auxiliary contact 7 lockings pin jack 3.At the end away from pin jack 3 bottoms of auxiliary contact, the contacting zone 15 of annular is set.The contacting zone 15 of the annular of auxiliary contact 7, along with first contact 1 vertically the direction of opposed second contact 13 exceed jack mouth 14.Assist the contacting zone 15 of the annular of contact 7, scribble a kind of coating of anti-ablation.
Make second contact 13 with respect to pin jack 3 mutually opposed and moulding in the same manner.Described second contact 13 is configured to the pivot pin shape.Second contact 13 has guiding jack 16 in addition, so that suit is to the director element 6 of pin jack 3 central authorities that are positioned at first contact 1.On the end face of an end of first contact 1, what second contact 13 was equipped with annular compresses zone 17.The zone 17 that compresses of described annular has the coating of anti-ablation and is configured to mutually opposed and identical with the contacting zone 15 of the annular of auxiliary contact 7.In addition, guiding jack 16 has also set the induction element 18 that radially protrudes.Described induction element 18 is the ring of electric insulation in a kind of groove that is embedded into guiding jack 16 in the present embodiment.Described ring be elastically deformable and be used to pass cover and install on the outer surface of director element 6 of first contact 1.
When being in the on off state of Electical connector shown in Figure 1, first contact 1 and second contact 13 are separated from each other (off-state), that is to say, first and second contacts 1,13 do not electrically contact.In order between first contact 1 and second contact 13, to set up a kind of current circuit of conduction, make first contact 1 do relative motion with respect to second contact 13 along longitudinal axis 2, be absolutely necessary.By means of this relative motion, can make on off state shown in Figure 1 " open " (off-state) and be converted on off state " pass " (on-state).In order to produce relative motion, for example can by a kind of in Fig. 1 unshowned drive unit, drive second contact 13 along longitudinal axis 2 and move towards the direction of first contact 1.
When second contact 13 moves to first contact 1, contacting zone 15 and the annular of second contact 13 that annular takes place earlier compressed contacting of regional 17 end face.When passing forward, will overcome the spring force of spring 10,3 bottom direction promotes auxiliary contact 7 along longitudinal axis 2 towards pin jack.
Electric discharge phenomena, such as connecting electric arc or disconnect electric arc, will be owing to the contacting zone 15 of the annular of the coating that has applied anti-ablation respectively and the first contacting that compresses zone 17 of annular, and appear between this zone.Along with contacting zone 15 with compress contacting of zone 16, first and second contacts 1,13 obtain a kind of indirect electric contact connection by the middle auxiliary contacts that connect 7.
Fig. 2 is illustrated in to push ahead between first contact 1 and second contact 13 and does relative motion.Fig. 2 represents that contact member 5 and auxiliary contact 7 and second contact 13 directly carry out the moment that electric contact is connected.At this constantly, the current circuit of the auxiliary contact 7 that connects by means of the centre between first and second contacts 1,13 is converted into first contact 1 and second contact 13 by the direct contacting of contact member 5 under the situation that auxiliary contact 7 is separated.Because auxiliary contact 7 prevented in the guider of machinery by means of the guiding of the electric insulation of insulating component 8, the current circuit with first and second contacts 1 that form by contact member 5,13 contacting circuit parallel appears.
It can also be seen that among this external Fig. 2 that induction element 18 is passed to the outer surface of director element 6, and second contact elements 13 is supported and is stabilized on the director element 6 by induction element 18 and guiding jack 16.Therefore, two contacts 1,13 are difficult to take place canting or inclinations each other.When pushing ahead between first and second contacts 1,13 when doing relative motion, auxiliary contact 7 continues along longitudinal axis 2 towards pin jack 3 bottom direction and moves.What go out as shown in Figure 2 is such, and after auxiliary contact 7 was passed by second contact 13, the convex shoulder 11,12 of director element 6 and auxiliary contact 7 had taken place to separate.Convex shoulder 11,12 separation, occur in time be separated the auxiliary current circuit of contact 7 between first and second contacts 1,13 before.Auxiliary contact 7 and director element 6 electricity mutually separate and by the mutual electric insulation in annular gap between director element 6 and auxiliary contact 7.Therefore only pass through the motion channeling conduct of 8 pairs of auxiliary contacts 7 of insulating component.Director element 6 only is a kind of for the backstop of the auxiliary contact 7 of restriction in the motion of pin jack 3 for auxiliary contact 7.Further push ahead and do relative motion along with first and second contacts 1,13, spring 10 also has been subjected to further compression.
Fig. 3 represents that first switch contact 1 and second switch contact 13 are in " pass " on off state (on-state) now, that is to say, will assist contact 7 to pass the terminal location that is arranged in pin jack 3 to it by means of second contact 13.The auxiliary contact 7 of electric insulation ground guiding in insulating component 8.Between first and second contacts 1,13, the contact member 5 of the groove 4 by being arranged in pin jack 3 obtains direct electric contact and connects.Auxiliary contact 7 no longer is the part of the current circuit between first and second contacts 1,13 when Electical connector is in on-state.Because the electric contact that compresses zone 17 of the annular of the contacting of the annular of auxiliary contact 7 zone 15 and second contact 13 is connected, auxiliary contact 7 has the current potential identical with first contact 1 and second contact 13.Because the auxiliary contact 7 of electric insulation ground guiding, therefore prevented and be formed at the parallel current circuit of current circuit between first and second contacts 1,13 by contact member 5, through mechanical guiding device.
Be starting point with state shown in Figure 3, to as discussed previously and put upside down in the order of the relative motion shown in Fig. 3,2,1, just can disconnect the contacting of first contact 1 and second contact 13.Second contact 13 shifts out from first contact 1.Owing to load by spring, can move auxiliary contact 7.The connection that continuation will be conducted electricity is from the direct contacting of first contact 1 and second contact 13; convert the indirect contacting of two contacts 1,13 under connecting in the middle of the auxiliary contact 7 to; until first contact 1 with till second contact, 13 electricity separate; wherein; because the end nipple in the contacting zone 15 of the annular of auxiliary contact 7 is for the trepanning 14 of pin jack 3; on auxiliary contact 7, arc phenomenon will occur, and protect first contact 1 not to be subjected to the infringement of this phenomenon thus.
